The pregnancy hormone, hCG
All mums and mums-to-be remember, when you did your first pregnancy test and it shows POSITIVE! Wooohhooo! But do you why?
It is because your body from day one of your pregnancy slowly starts to produce a hormone called, human chorionic gonadotropin, better known as hCG.
The level can be only detected from around two weeks after you got pregnant, as that’s when you have enough in your urine for the test to turn positive.
The hormone hCG nourishes the egg after it has been fertilized and becomes attached to the uterine wall.
During pregnancy hCG levelsdouble every 72 hoursand reach the maximum between week six and ten of your pregnancy. That’s also the time when loads of pregnant women will start to have some serious morning sickness… (now you know ladies why).
Afterwards, hCG will slowly start to decrease the levels will begin to decrease as the placenta starts to form fully and will level once the placenta is fully formed.
Low and high levels of hCG
Having very high hCG during pregnancy is very rare however having low hCG during pregnancy can be a sign of miscarriage or other problem, such as the embryo implanting outside of the uterus.
